RAILRGAD-TIE.

T all whom 't1/may concern.'

Beit known that l, DANIEL S. GRAEFF, a citizen of the United States, residing at Hershey, in the county of Dauphin and State of Pennsylvania, have invented a. new and useful Railroad-Tie, of which the following is a specification.V

The present invention relates to improvements in railroad ties, one object of the invention being the provision of a tie, either of a reinforced concrete or steel nat-ure, in which are shaped to be positioned spike receiving plugs, the upper surface and sides of which are adapted to be in the same plane with the upper surface and side faces of the tie to receive a tie plate which is spiked with the rail to the spike receiving wooden plug and coacts with the tie to lock the plug against lateral movements.

A further object of the present invention is the provision of a reinforced concrete tie provided with longitudinal reinforcements,

one reinforcement of which is formed in the shape of a receptacle to provide a proper seat for two rail carrying blocks, said blocks being so construct-ed that the upper surfaces are exposed to receive the spikes for securing the rails thereto.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what isclaimed without departing from the spirit of the invention.

In the drawings-Figure l is a view of the present tie in use, a portion of the tie being shown in longitudinal 4section to properly show the position of the rail and one of the spike receiving blocks in place. Fig. 2 is a section taken on line 2 2 of Fig. l. Fig. 3 is a section taken on line 3-3 of Fig. l. Fig. 4t is a perspective view of one of the spike receiving blocks removed. Fig. 5 is a perspective view of the tie plate.

Referring to the drawings, the numeral l designates the tie body, which in the present instance is shown as composed of a concrete body, reinforced by the two lower twisted longitudinal reinforcing rods 2 and the channel plate 3, the walls of which are disposed to be positioned in the concrete body above the rods 2 as clearly illustrated in Fig.

2, the walls and bottom of the channel plate 3 being perforated to permit of the passage therethrough o-f the concrete material, whereby when the same is properly coalesced, the channel plate 3 is held iixedly within the concrete body. I

Seated within the concrete and within the channel plate 3 at the proper position from the end of the tie body l, are the wooden blocks 6, each one of which, as clearly shown in F lgs. l and 3, is provided with the sharpened ends 6', which when the block is properly positioned within the concrete body, as illustratedin Figs. l and 3, and when the body of concrete within the channel plate 3 has coalesced, are firmly held against upward movement, while the rims S of the tie plate form means to prevent transverse or lateral movement of the plug. The upper surfaceof the respective blocks 6 terminate at a point in the same plane with the upper surface of the tie body l, to receive the tie plate 7 said tie plate being provided with downwardly extending parallel rims 8 which lit astride upon the upper corners of the tie body 1, as clearly illustrated in Fig. 3, their projecting ends 9 being disposed beyond the meeting portion between the block 6 and the adjacent part of the concrete body and thus hold the block within the tie.

rlhe tie plate is provided with spike receiving holes 10, for the reception of the spikes 11 which are driven through such apertures or openings 10 into the wooden block 6, so that the rail is held in the position as clearly shown in Fig. l.

The blocks 6 are preferably composed of a treated wood, such as creosoted wood, so that the life thereof when embedded within the tie will be substantially as long as that of the tie body itself, the tie plate being of such a length as to extend and prevent to a great extent, the permeating of or the entering of water into or upon the upper surface of the block 6, the flanges S constituting a means to prevent the tie plate from turning relatively to the tie body l, thus rigidly securing the rail in place against spreading or inward or outward tilting, but allowing, as is the usual practice, the necessary longitudinal expansion and contraction.

l/Vhat is claimed is:

l. A railroad tie, the body of which is composed of reinforced concrete, a channel plate carried in the body and forming a reinforcing member longitudinally thereof,

two spike receiving members mounted in the concrete body within the channel plate adjacent the ends thereof, the upper' surfaces and side faces of the spike receiving blocks being in the same plane with the upper surface and sides of the concrete body, two tie plates, one to each spike receiving block fitting upon the upper surface thereof and the adjacent portions of the side surfaces of the body and also the sides of the block, andv spikes piercing the tie plates and blocks.

2. A railroad tie, the body of which is composed of reinforced concrete, a channel plate carried in the body and forming a re-A inforcing member longitudinally thereof, two spike receiving blocks mounted in the concrete body within the channel plate adj acent the ends thereof, the upper surfaces of the spike receiving blocks being in the same plane with the upper surface of the concrete body, two tie plates, one to each spike receiving block fitting upon the upper surface thereof and the adjacent portions of the top surface of the body, said plates being provided with two parallel flanges adapted to fit upon each side of the concrete body to hold the plate and block against transverse movement.

In testimony that I claim -the foregoing as my own, I have heretopalfixed my signature in the presence of two witnesses.
